S-94709A157 0.656" ID x 1.25" OD Bonded Sealing Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction for long-lasting performance in harsh environments
• Excellent sealing capability provided by the bonded black Neoprene rubber seal that prevents fluid and gas leakage
• Wide temperature tolerance from -40°F to 250°F, ensuring reliable operation in extreme thermal conditions
• Optimized dimensional fit with 0.656" ID and 1.25" OD specifically designed for 5/8" screw applications
• Enhanced durability through the metal-to-rubber bonded construction that resists separation under stress
• Consistent sealing performance maintained by the Durometer 65A Neoprene seal offering ideal compression and recovery
• Versatile industrial application suitability for machinery, piping, and equipment requiring reliable sealed fastening solutions

Professional Applications & Engineering Value

This metal bonded washer combines the structural integrity of 18-8 Stainless Steel with the sealing elasticity of black Neoprene rubber to solve critical industrial challenges. Engineers specify this component for applications where both corrosion resistance and fluid/gas sealing are paramount, such as in chemical processing equipment, marine hardware, and outdoor machinery. The bonded construction ensures the seal remains securely attached to the metal washer during installation and vibration, eliminating common failure points. With its ability to perform across a broad temperature range (-40°F to 250°F), this washer provides reliable service in environments subject to thermal cycling, while the precise dimensions (0.656" ID x 1.25" OD) guarantee proper fitment on 5/8" fasteners in demanding assembly operations.

Specification Summary & Compliance

This metal bonded washer features inch system dimensions with 0.656" inner diameter, 1.25" outer diameter, and 0.150-0.182" thickness range. Manufactured from 18-8 Stainless Steel with a bonded Neoprene rubber seal rated at Durometer 65A hardness. The component is designed for 5/8" screw applications and operates effectively within a temperature range of -40°F to 250°F. While hardness is not rated for the metal component, the assembly meets industry standards for bonded washers and is suitable for applications requiring basic corrosion resistance and sealing performance.
